Internet data is introduced into public health arena under the features of fast updating and tremendous volume. Mining and analyzing internet data, researchers can model the internet-based surveillance system to assess the distribution of health-related events. There are two main types of internet-based surveillance systems, i.e. active and passive, which are distinguished by the sources of information. Through passive surveillance system, information is collected from search engine and social media while the active system gathers information through provision of the volunteers...

Lymphocytes undergo dynamic changes in gene expression as they develop from progenitor cells lacking antigen receptors, to mature cells that are prepared to mount immune responses. While transcription factors have established roles in lymphocyte development, they act in concert with post-transcriptional and post-translational regulators to determine the proteome. Furthermore, the post-transcriptional regulation of RNA regulons consisting of mRNAs whose protein products act cooperatively allows RNA binding proteins to exert their effects at multiple points in a pathway...

The uropygial gland is a holocrine complex exclusive to birds that produces an oleaginous secretion (preen oil) whose function is still debated. Herein, I examine critically the evidence for the many hypotheses of potential functions of this gland. The main conclusion is that our understanding of this gland is still in its infancy. Even for functions that are considered valid by most researchers, real evidence is scarce. Although it seems clear that preen oil contributes to plumage maintenance, we do not know whether this is due to a role in reducing mechanical abrasion or in reducing feather degradation by keratinophilic organisms...

As highlighted in a recent editorial, the ageing population and burden of frailty amongst those aged 60 years and older represents an impending challenge for individuals and health care systems globally (Smith & Kydd 2017). As frailty is largely considered a geriatric syndrome, research has primarily occurred within elderly community dwelling populations (Fried et al. 2001). However, it is important to highlight that not all older people are frail; and conversely not all younger people are non-frail. With frailty research expanding its scope beyond geriatrics over the last 2 decades, our understanding of this syndrome and its complexities has progressed...

Parkinson's Disease (PD) is the second most common neurodegenerative disease in the world, however, there is no cure for it. Current treatments only relieve some of the symptoms, without ceasing the disease, and lose efficacy with prolonged treatment. Considerable evidence shows that persistent inflammatory responses, involving T cell infiltration and glial cell activation, are common characteristics of human patients and play a crucial role in the degeneration of dopaminergic neurons. Therefore, it is important to develop therapeutic strategies that can impede or halt the disease through the modulation of the peripheral immune system by aiming at controlling the existing neuroinflammation...

Loneliness in later life is a common problem with poor health outcomes. However, interventions to prevent or ameliorate loneliness have a weak evidence base. The views of older people experiencing or at risk of loneliness in the community are important in identifying features of potential support, but have been little studied. Twenty-eight community dwelling people, aged 65 and over who reported being 'lonely much of the time' or identified as lonely from the de Jong Gierveld six-item loneliness scale in a larger study, participated in in-depth interviews, between June 2013 and May 2014...

Objective: Exercise training provides a cornerstone of pulmonary rehabilitation (PR) in COPD-patients. However, the components of the training are not yet fully investigated. We conducted a randomized controlled trial to investigate the effectiveness of a sensory-motoric training (SMT) in comparison to a conventional strength training (KT) according to the physical performance. Patients and Methods: 43 COPD patients were randomized and participated either in the intervention group (SMT = 30 minutes SMT per day) or in the control group (KT = 30 minutes KT per day)...

Obstructive sleep apnea is one of the most common diseases in Western industrialized countries. A variety of conservative and surgical treatment options are available for its treatment. In recent years, selective upper airway stimulation (sUAS) has been shown to be effective and safe. Different biomarkers have been investigated as predictive clinical success factors in a number of clinical trials. Age does not matter in sUAS, as compared to its predictive role in other therapies. Weight seems to play a limited role, depending on drug-induced sleep endoscopy to rule out a complete concentric collapse with an increased body mass index...

In Europe, ultrasound (US) is the diagnostic gold standard for the visualisation of parotid gland disorders. While high-resolution B-mode US reliably visualises focal lesions, its diagnostic capacity to distinguish tumour entities or to characterise diffuse lesions remains poor. Strain elastography (SE) and shear wave elastography (SWE) are novel imaging techniques that provide additional information about tissue elasticity. SE analyses the strain or displacement in response to force or compression and, therefore, shows the relative tissue elasticity within a selected region of interest (ROI)...

The immune system functions to defend the organism against infectious microorganisms but also against transformed cells. This key role of the immune system, in particular cancer-specific T cells, in eliminating cancer cells is compromised by various immune escape strategies employed by cancer cells and the cancer microenvironment. Here, we review the current knowledge about the immune escape mechanisms of cancer and the attempts to reconstitute cancer-specific immunity by using checkpoint inhibitors in head and neck squamous cell carcinoma...

Thyroid cancer derived from follicular cells (TCDFC) comprises well-differentiated (papillary and follicular) carcinoma, poorly differentiated carcinoma, and anaplastic carcinoma. Papillary thyroid carcinoma is the most common endocrine cancer, and its incidence is steadily increasing. Lethality and aggressiveness of TCDFC is inversely correlated with differentiation degree. In this review, an emphasis has been put on molecular markers involved in tumorigenesis of thyroid carcinoma with a focus on aggressive histotypes and the role of such biomarkers in predicting thyroid cancer outcome...

Invasive aspergillosis (IA) is one of the most difficult to treat and, consequently, one of the most lethal fungal infections known to man. Continued use of immunosuppressive agents during chemotherapy and organ transplantation often leads to the development of neutropenia, the primary risk factor for IA. However, IA is also becoming more appreciated in chronic diseases associated with corticosteroid therapy. The innate immune response to Aspergillus fumigatus, the primary agent in IA, plays a pivotal role in the recognition and elimination of organisms from the pulmonary system...

Pheochromocytomas (PCC) and sympathetic paragangliomas (PGL) are rare neuroendocrine tumors, which derive from chromaffin cells occurring in the adrenal medulla and extra-adrenal sympathetic paraganglia. PCC and PGL are often benign, catecholamine-producing tumors, responsible for a myriad of symptoms that may be potentially hazardous to the patient. In contrast, nonsecreting parasympathetic PGL, derived from chief cells, develop mainly in the head and neck region. Although PCC/PGL are more commonly sporadic tumors, germline mutations are present in up to 40% of the patients, ranking these tumors among those with the highest degree of heritability...

The use of agents able to modulate the immune system to induce or potentiate its anti-tumour activity is not a new strategy in oncology. However, the development of new agents such as immune checkpoint inhibitors has achieved unprecedented efficacy results in a wide variety of tumours, dramatically changing the landscape of cancer treatment in recent years. Ipilimumab, nivolumab, pembrolizumab or atezolizumab are now standard of care options in several malignancies and new indications are being approved on a regular basis in different tumours...

Prostate cancer (PCa) shows a broad spectrum of biological and clinical behavior, which represents the epiphenomenon of an extreme genetic heterogeneity. Recent genomic profiling studies have deeply improved the knowledge of the genomic landscape of localized and metastatic PCa. The AR and PI3K/Akt/mTOR signaling pathways are the two most frequently altered, representing therefore interestingly targets for therapy. Moreover, somatic or germline aberrations of DNA repair genes (DRGs) have been observed at high frequency, supporting the potential role of platinum derivatives and PARP inhibitors as effective therapeutic strategies...
